Westoby was born in 1815 at Emberton, Buckinghamshire, the son of Amos Westoby who had graduated from St Edmund Hall, Oxford and been ordained the previous year; his mother Mary died in 1818. He received his M.A. in 1839 from Trinity College, Cambridge.
Philately
Westoby began collecting stamps in 1861 or 1862. He was resident in Paris for some time where he met his lifelong friend Frederick Philbrick in 1863. He discovered the first known copy of the Spanish 2r 1851 error of colour in 1867. He was not a founder of The Philatelic Society, London, now The Royal Philatelic Society London, but was a member from at least November 1869, shortly after the Society's founding, when he read a paper titled "Envelopes of Germany". At one point he resigned and was later re-elected, possibly because membership of the society was at one time limited to residents of London. Westoby was a prolific contributor to philatelic journals under the pen name "A Parisian Collector", including The Philatelist and The Stamp-Collector's Magazine. He was the editor for four years of The Philatelic Record and also of Alfred Smith & Co.'s Monthly Circular from 1878. When his European collection was dispersed, many fine items found their way into the Tapling Collection.
